Playtime?

About this book

Bedtime can be a challenge for the best of us. But when you're a fun-loving, overactive pet gorilla, bedtime is downright hard. Who would want to go to sleep when Playtime is so much more fun? But the gorilla's responsible friend thinks enough is enough; no more fun and games. It's not Playtime--It's Bedtime! So the boy turns off the lights and the gorilla goes.
